your question contains only 'O' (the letter), which is right .. zeros are not correct. Glad you solved it !

it should work .. can you supply the full game ?

Phalanx makes illegal move

how to add a java engine ?

it seems SOME engines have this issue .. the programmer should "feed" the proper MPV list to Scid, so i guess this is NOT a Scid error ..

you write " setting the notation window to column view is just a preference" .. i did not discover that setting .. i only find menu Options / Preferences / Moves but there is no option as you suggest .. where in the menus do i find the 2 column setting ?

Btw. the game notation in your screenshot has another format as mine : you have 2 columns, but normally SCID gives one line with the variation - you must have typed this notation yourself !?

I also use SCID v4.7.1 on Debian (Xubuntu 20.04) but i can NOT reproduce this behaviour : dropping the King on its Rook does not castle, the King flips back to its original square .. indeed, because KxR is an illegal move : Kxh1 never comes .. i almost think you are trolling .. can you attach a short screencast of such castling, including the generated notation ?
